srnme-wnienn To all whom, it may concern: p 1

Be'it known that I, FRANK Hi ALLEN, a

citizen of the United States, residing at McNabb, in the county ofPutnam and State of Illinois, have inventednew and useful Improvementsin Spring-Wheels, of which the followingis a specification.

This invention relates to sprin wheels,

the object in view being to provi e a con-' structionof springvvheel'fwhich will enable the ordinary'pneumatic'tire to be dispensedwith, while retaining the necessary resilient properties in the wheel toabsorb all jar and vibration and prevent the transmission of the same tothe axle and body of the vehicle.

With the above and other objects in View, the invention consists in theconstruction,

combination and arrangement of parts, as-

will be hereinafter: more fullyldescribed, illustrated in theaccompanyingdrawings, and pointed out in the claim hereunto appended;

In the drawings: Figure is a side elevation of a Wheel, partlyin'section, illustratingthe present invention. fFig. 2 is-a detailperspective view of one of the springs.

Fig. 3 is a detail perspective view ofone of the keeper plates, i

The wheel fil ,ustrated the accompanying 'drawihgs, embodies a rimor'felly '1 adapted to receive no n-puncturable tire oiany construction,whether of metal, rubber, or the like, and a hubQ of'any suitabledescription,

In lieu of the ordinary wooden spokes which conne ctthe hub and telly, Iemploy a series of spring spokes. each of which is formed of a flatstrip of spring metal which is bent and recurved in opposite directionsto form the oppositely projecting convolu;

tions or bends 3 connected by the integral comparatively straightportions 4, as illustrated in Figs. 1 and 2, the portions 4c extendingsubstantially at right angles to the gen.- eral direction of the springsfrom the hub to the telly".

The, end portions of the springs are en larged and tapered, as shown at5, and at each end spring is provided with a men 6 which is smaller indiameter than the specification of Letters Patent.

larger end portion of the part 5, so as to leave a shoulder 7 whichbears against the outer face of the hub 2, or the inner face of thetelly 1, as the case may be;

v The tenon'e at the inner end of the spring spoke is received in amortise 8 in the hub,

and may besecured-fixedlytherein by a pin .9 inserted transver e1ythrough the'hub and said tenon. The tenon 6 at the outer end of thespringspoke is likewise inserted in a l 'mortise 10 in the felly andsecured by means of a transverse pin or key 11.

In "order to firmlyattach the opposite ends of thespring spoke "to thehub and telly,

keeperplates lZ and '13 are provided, each pf said plates'being; formedwith a central countersunk or tapered hole 14 which fits over theenlarged tapered end portion ofthe spring spoke, asrclearly showninIFig.
